BRACE FO R SPRING BED-BOTTOMS SPECIFICATION forming part of LettersPatent No. 647,424, dated April 10, 1900.

Application filed May 26, 1899- Serial No. 718,431. (No model.)

To (LZZ whom it may concern.-

Beit known that I, NIELS PETERSEN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Bed-Springs, of whichthe following is a specification.

My invention relates to improvements in braces for spring-beds; and itsobject is to so brace the bed that it will, as soon as weight is placedupon it, become rigid so far as lateral movement is concerned. Iattainthis object by the mechanism illustrated in the accompanying drawings,in which-- Figure 1 is an elevation of a portion of a spring, showingthe application of my brace. Fig. 2 is a plan of the same. Fig. 3 is aperspective of my cheaper and more commonlyused form of brace, and Fig.4 is a modified form of the same.

Similar letters refer to similar parts throughout the several views.

In the accompanying drawings, A repre-' sents the border of the bed.

B represents the spring, and O and D represent my brace. This brace ismade of two pieces of wire, bent twice at right angles, so that the bodymay be passed through the tube D, and the ends 0 will project at rightangles therefrom, the bent ends of each wire arranged to lie in the sameplane and the bodies adapted to form ahinge or pivot, so that the endsof the wire may work freely toward and from each other, as indicated bythe dotted lines in Fig. 1, to correspond with the compression andexpansion of the bed-bottom. At the ends of these arms I form eyes 0, bymeans of which I secure the braces to the border of the bedbottom or tothe top and bottom of the springs, as indicated at O and at O and c inFig. 2. The construction of this brace is such that when the springs arein their normal posi-' tion, with no weight upon them, they may beeasily swayedlaterally or longitudinally; but when weight is placed uponthe springs one arm of the brace is thrown in contact with one surfaceof the bed-bottom, as indicated by the dotted lines in Fig. 1, and holdsthe springs so firmly to position that no lateral or longi tudinalmotion can be given to the upper surface.

In Fig. 4 I show the brace constructed with out the use of the tube D,which is accom plished by simply winding one wire around the other, asat D, to form the pivot or hinge joint. Both forms are applied the same,and

their action is the same, so that the choice between the two forms issimply a matter of taste, convenience, or expense.

Having thusfully described my invention,

what I claim as new, and desire to secure by free vertical action,substantially as and for the purpose set forth.
